Hi there,
So I went back and created a custom search in the Google API console. It worked very well, returns a Json list of Data, Now I can can build on this by:
-
Parsing the JSON response: If you want to extract specific data like URLs or descriptions from the search results,
-
Handling different queries: I can dynamically change the search query based on input, sensors, or other conditions in the project.

#include <WiFi.h>
#include <HTTPClient.h>
const char *ssid = "GlassSurf-2.4";
const char *password = "SeeedStudio :-p ";
// Google API Key and CSE ID
const String apiKey = "REPLACE with YOUR KEY "; // Your API key
const String searchEngineId = "REPLACEwithYOURs"; // Your CSE ID
// Search query
const String searchQuery = "Arduino project"; // you can set this to whatever your searching for
void setup() {
Serial.begin(115200);
// Connect to Wi-Fi
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi...");
}
Serial.println("Connected to WiFi!");
Serial.print("IP Address: ");
Serial.println(WiFi.localIP());
// Perform Google search
googleSearch(searchQuery);
}
void googleSearch(String query) {
if (WiFi.status() == WL_CONNECTED) {
HTTPClient http;
// Make sure to replace spaces with '%20' for URL encoding
String encodedQuery = query;
encodedQuery.replace(" ", "%20");
// Correct URL formatting for Google's Custom Search API
String url = "https://www.googleapis.com/customsearch/v1?key=" + apiKey + "&cx=" + searchEngineId + "&q=" + encodedQuery;
Serial.print("Requesting URL: ");
Serial.println(url);
// Make GET request to Google Custom Search API
http.begin(url);
int httpCode = http.GET();
// If the GET request was successful
if (httpCode > 0) {
String payload = http.getString();
Serial.println("Search Result:");
Serial.println(payload); // Print the raw JSON result from the API
} else {
Serial.print("Error on HTTP request: ");
Serial.println(httpCode);
}
http.end(); // Free resources
} else {
Serial.println("WiFi not connected");
}
}
void loop() {
// Nothing to
}
The output is Long so I’ll only add some of it.
Connecting to WiFi...
Connected to WiFi!

Works GREAT!
